CHA8610-99F
15W X Band High Power Amplifier
GaN Monolithic Microwave IC
Description
The CHA8610-99F is a two stage High
Power Amplifier operating between 8.5 and
11GHz and providing typically 15W of
saturated output power and 40% of power
added efficiency.
It is designed for a wide range of
applications, from military to commercial
communication systems.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form.
